Hallo Sema,
I believe the function you are looking for is called set_center_freq, when using the gnuradio interface to the USRP. So it should be: usrp = uhd.usrp_source(device_addr = addr, io_type = uhd.io_type.COMPLEX_FLOAT32, num_channels = 1) usrp.set_center_freq(1.03e9, 0) # Passing the channel as an argument is optional Regards Andreas Von: discuss-gnuradio-bounces+andreas.schantin=uni-siegen...@gnu.org [mailto:discuss-gnuradio-bounces+andreas.schantin=uni-siegen...@gnu.org] Im Auftrag von s k Gesendet: Donnerstag, 20. Juni 2013 08:59 An: discuss-gnuradio@gnu.org Betreff: [Discuss-gnuradio] Setting Intermediate Frequency in Python I am using this code to set an intermediate frequency in Python platform: usrp = uhd.usrp_source(device_addr = addr, io_type = uhd.io_type.COMPLEX_FLOAT32, num_channels = 1) usrp.set_rx_freq (0, 1.03e9) but I am getting an error as: AttributeError: 'uhd_usrp_source_sptr' object has no attribute 'set_rx_freq' But i saw this in some USRP documents. Is this an old and out of use code? How can I set the IF. (My purpouse of using IF is cancelling the unreal center peak. http://lists.gnu.org/archive/html/discuss-gnuradio/2012-08/msg00032.html) Sema
